THE VAPOURER MOTH (DISPERSAL)
On 24/09/2010 while walking I found the caterpillar of the Vapourer feeding on willow ,its very distictive and quite colourful.
Given that the female can"t fly,the dispersal of the species is dependant on how far the caterpillar can travel from the pupating site,so it is quite local, and very dependent on its habitat not changing suddenly. Allowing for predation by birds etc it has a tough battle to survive without any environmental change.Another reason why we have to be careful in our environmental actions.
